Kelvin was founded in New York City in 2013 by Marshall Cox, a material science engineer with a Masters from Cornell University and a PhD in electrical engineering from Columbia University. The inspiration for the company came from Marshal’s twin brother, who complained about the heat in his apartment while staying with him for a month. Marshal came up with a solution that eventually became the basis of Radiator Labs, the original name of the company. Unknowingly, from that day forward, he set out on a mission to decarbonize legacy building’s heating and cooling systems. After conducting several successful pilots, Radiator Labs launched a full-scale commercial deployment of the Cozy system in 2016. The Cozy is a retrofit device that encloses radiators and controls their heat output. Radiator Labs participated in studies with NYSERDA and Con Edison, consistently demonstrating savings on heating bills between 25% and 40% with the Cozy system.
